Does anyone know if replacing the section of exhaust pipe between clamps that connect to the down pipes and the clamps that connect to the rear muffler with possibly some custom piping would pick up anymore sound? Is there some type of resonator built into the pipes as I can't see anything obvious from the outside, it already looks as though this section could be straight through.

Love the car but feel its just to quiet and I want to be able to make a change to the exhaust that is easily reversible down the track.
